I really am stuck! Here are my many questions and dilemmas:

I love the names Aviana (nn Ava) and Eliana (nn Ellie) but they are way too similar for sibling names. Which name do you like better and are there any variants that don't end in ana/ann that are just as beautiful?

I slightly prefer Aviana based on the nickname option of Ava because I really dislike the nickname Ellie. Aviana is beautiful and unique, while Eliana is the safer option. Eliana can quickly blend with all the other El- names, as can Aviana but using the full Aviana excites me more than hearing Eliana. How about Viviana? Vivi is an adorable nickname...

I'm leaning towards Eliana, but both are beautiful names. I think ElianaJoy is too expected as another poster said, I like ElianaJoyce better. I think Joyce when paired as Eliana's middle can work through a person's life without sounding too too cutesy. But either would be pretty, it depends on personal preference. Avians Rose over SiennaRose. Cate-Kate is a sweet name, I think it is really pretty.
